yín 夤*[ɢ](r)ə[r] “small of the back” : WT sgal-pa “back of man, back of beast of burden, small of the back”

As part of a set of cognate words including the verb ‘gel/bkal/dgal/khol “to load, lay on a burden” and khal “burden, load”, WT sgal-pa “small of the back’ has been compared to 何 *[g]ˤajʔ > haX > hè “carry” by Gong (System of Finals in Proto-Sino-Tibetan #165). A comparison between two words meaning “small of the back” is more specific than one between two words meaning “to carry”. The more specific comparison should be preferred. The small of the back—the narrower part of the back, in the lumbar region—is where pack animals are made to carry burdens. This implies that the Tibetan word-family (“to load/burden/small of the back”) is built around the body-part term. The nature of the s- element at the beginning of the word is uncertain.

2. “to pass”

The character 羨 has several pronunciations and meanings. In the pronunciation MC yen it writes a word meaning “pass, go beyond”, for which a WT comparison presents itself:

The WT verb rgal/brgal/brgal/rgol has also been compared to 河 *[C.g]ˤaj > ha > hé “river, especially the Yellow River”. This comparison is semantically not compelling since, especially where it crosses the early Chinese territory, the Yellow River certainly cannot be crossed on foot, in any season. This comparison seems to have been proposed primarily because of the phonological parallel it provides with the comparison for “small of the back”: i.e. OC gal(x) (in Gong’s system) to WT /gal/, with both Chinese words written by means of the phonetic 可.

In B&S reconstruction, in both comparisons, initial *[ɢ] is ambiguous for *N.q and *ɢ and the presence of medial *r cannot be excluded—although we omitted any explicit mention of it in our reconstruction *[ɢ]a[n]. Final *[n] is ambiguous for *-r. The vowel correspondences OC *a : WT a and OC * ə : WT a are regular, and so are the correspondences if codas, assuming final *[n] can be disambiguated to *-r in “pass, go beyond”.

In a recent post on ‘water’ and ‘lip’ (https://stan.hypotheses.org/20) I identified a correspondence indicating PST *-ur:

OC *-ur, Bodo -əy, Lushai -ui, -Proto-Karen *-ej, WT *-u.

‘Egg’ would fit into that correspondence beautifully —the coda in the OC word is ambiguous for *-r—if it was not for a rare WT word for ‘egg’:

Written Tibetan

Boro (Bhat)

Lushai (Lorrain)

Proto-Karen (Luang.)

OC (B-S)

PST (tentative)

! thul ‘egg, testicle’

dəy ‘egg’

tui ‘egg’

Ɂdej B ‘egg’

tʰu[n] ‘egg’

#tʰur

chu ‘water’

dəy ‘water, river’

tui ‘water’

thej A ‘water’

s.turʔ ‘river, water’

#s-turʔ

mchu ‘lip’

(gusu)təy ‘lip’

(not cognate)

n.a.

sə.dur ‘lip’

#m-tur

The expected rhyme correspondence for WT is -u, as shown by ‘water’ and ‘lip’. What is going on ?

Here is an idea. OC had an <r> infix that it shares with Austronesian and it would make sense if TB did, too. Some minimal pairs involving medial -r- and showing semantic alternations very much like Chinese can be found in TB languages: medial -r- calls attention to the distributed character of objects or actions. I treat medial -r- as the <r> infix in the pairs below:

Jingpo: phun31 ‘of lumps or pimples, to appear on the body’ : ph<r>un31 ‘pimples, lumps on the body; to appear on the body, of pimples or lumps’

Such pairs are never found with alveolar initials; Zev Handel has claimed that *tr- clusters do not reconstruct to PTB or even PST (Handel 2002). Another possibility exists: *tr clusters (including infixal *t<r>- clusters) existed in PST but merged with *t- in PTB (this would constitute a TB innovation).

There are no WT words of the shape CrVr, that is, with both medial -r- and final -r. In my first post to this blog (https://stan.hypotheses.org/11) I suggested that when that situation arose, for instance after the metathesis of preinitial -r, final -r dissimilated to -l. Supposing that a constraint on medial and coda r already existed in PST, a PST doublet involving a root *thur and the <r> infix would alternate *thur vs. *th<r>ul. By the changes described in my earlier posts, this doublet would evolve to PTB *thuy vs. *thul. In WT, *thuy would evolve to thu (chu if palatalized); but WT actually thul reflects PST *th<r>ul, the infixed variant.

There exist occasional cases of alternations between words with preradical d- and r- in Old/Written Tibetan (OT/WT), for instance dba vs rba ‘wave’, dgu ‘nine’ vs. rgu ‘many’. I am uncertain of the nature (phonological ? dialectal ?) of these alternations. At the same time, rb-type onsets are rare in Written Tibetan and rp- onsets are entirely absent. In a blog dated 19/11/2015 (https://panchr.hypotheses.org/527) Guillaume Jacques proposed that a metathesis has affected pre-Tibetan *rp-, changing it to WT phr-; this is supported by a comparison between WT phrag-pa and Japhug tɯ-rpaʁ, both ‘shoulder’, both forms being derivable from an earlier *rpak. Combining Jacques’ hypothesis with r-/d- preradical doubleting stimulates us to look for db-/br and dp-/phr- doublets. Here is an apparent instance of a db-/br- doublet: dbur ‘to grind, pulverize; flour’ vs. brul ‘very small broken pieces’. These two forms could go back to a dbur vs. rbur doublet, assuming the evolution from rbur to brul involves a dissimilatory change of final -r to -l.
